+ NOTE: this version of pwc is an unofficial (modified) release of pwc & pcwx
+ driver and thus may have bugs that are not present in the original version.
+ Please send bug reports and support requests to <luc@saillard.org>.
+ The decompression routines have been implemented by reverse-engineering the
+ Nemosoft binary pwcx module. Caveat emptor.
